BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 398,495, dated February 26, 1889.

Application filed November 16, 1888. $erial No. 290,990. (No model.)

2' all whom it may concern:

Be it known that 1, JOHN H. COREY, a citizen of the United States, residing at Pittsfield, in the county of Berkshire and State of Massachusetts, have invented new and useful Improvements in Bottle-Stoppers, ofwhich the following is a specification.

This invention relates to inuirovements in bottle-stoppers; and it consistsuilllla certain novel construct-ion and combination of devices fully described hereinafter in connection with the accompanying drawings, and specifically pointed out in the appended claims.

In the drawings, Figure .l is a side view of the valve.

the improved stopper applied in the operative position to a bottle or flask. Fig. 2 is a vertical central sectional view of the same with the valve raised or closed. Fig. 3 is a similar view of the stopper with the valve down or open, this section being taken at right angles to that shown in Fig. 2. Fig. l is a detail view of the valve and its handle or loop. Fig. 5 is a transverse section through the disk. Fig. 6 is a detail perspective view of the washer.

Referring by letter to the drawings, A designates a bottle or flask, around the neck of which is arranged the ring B, and to this ring is pivoted the lever G in any ordinary or preferred manner.

The metallic disk D, which fits over the f month of the bottle, is provided in its opp0 2 site sides with sockets (l d, in which are engaged the free ends of the swinging loop E, and the closed end of this loop is connected to an intermediate point of the lever C in the ordinary or preferred manner. The disk D is provided with a central vertical bore, F, and a depending barrel, D, registering with the said bore, and the lower end of the said barrel is provided with a lateral flange, f.

The elastic washer G is provided with a central vertical perforation, g, which fits on the barrel D, and an internal peripheral groove, g, near the lower end of the perforation g accommodates the annular flange on the lower end of the barrel. The washer is provided at its lower side below the lower end of the barrel with an inward-extending lip, 9 in the lower side of which is formed the depression or valve-seat 9 The washer is further pro vided near its upper end with an outwardextending flange g which bears on the upper edge of the bottle and is adapted to be compressed between the bottle and the under side of the disk D. The portion of the washer above the out-ward-extending flange forms a vertical flange, (shown clearly in Fig. 6,) which is compressed when the disk is drawn down, and therelrv forms a tight joint around the barrel D.

The valve ll consists of a small metallic disk fitting in the depression or seat in the lower side of the washer, and K represents a handle or loop which extends downward through the bore of the disk D, and is screwed at its lower end in a threai'led perforation in This handle or loop is preferably made of spring-wire, and is reduced or tapered toward its lower end, the upper end being too large to pass through the bore.

Vertical grooves I I are formed in opposite sides of the bore of the disk D, and when the handle or loop is turned so thatits sides fit in the said grooves the valve is allowed to drop away from its seat; but in order to remove the sides of the handle or loop from the said grooves and turn the same the 'alve must be drawn up tightly against its seat. After the valve has been drawn up to its seat and the handle or loop is turned the latter cannot be forced down into the bore, and therefore the valve is locked in its closed position. Shallow notches 2' i are formed in opposite sides of the bore of the disk intermediate between the grooves I I, and the sides of the handle or loop are engaged in these notches when the valve is closed.

The advantages of the improved stopper are that the valve may be opened and the bottle filled through the bore of the stopper. The bottle may be emptied through the said bore, or when partly emptied maybe readily closed again. The stopper does not prevent the bottle from being cleaned on an ordinary bottlewashing machine. 7

Having thus described the invention, I claim 1. In abottle-stopper, the combination of the disk provided with a depending barrel, the washer encircling the barrel and provided near its upper end with a lateral flange hear ing on the top of the bottle, and a vertical flange projecting above the lateral flange, and

means to draw the disk downward, substantially as specified.

2. The eo1nbination,with a stopper provided with a central bore having diametrieally-opposite tapering grooves in its sides, of the valve fitting the lower end of the bore and the handle or loop passing through the bore and tapered toward its lower end to fit in the said grooves to allow the valve to drop, substantially as specified.

In a bottle-stopper, the combination of the disk provided with a depending barrel and having a central vertical bore, the lateral flange f on the lower end of the barrel, the Washer fitting around the barrel and provided with an internal groove, g, fitting over the fiangef, and an inward-extendin lip, g fitting over the lower end of the barrel and provided with a depression or "alveseat, and the valve l fitting in the said depression or valve-seat and provided with a'handle or loop extending up ward through the bore, substantially as specified.

4. The combination of the disk D, bearing on top of the bottle and having a depending barrel extending into the neck of the bottle, and provided withgrooves I I and notehesi 2? in diametrically-opposite sides of its bore, the valve fitting against the lower end of the barrel, and the handle or loop K, connected to the valve and extending through the bore of the barrel and adapted to have its sides engaged in either the grooves I or the notches '1 sub stantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

JOHN H. COREY.
